or MAKING 'SHE SAME.

To all whom it may conce-fn:

.Ue it known that EDWARD J'. GALIAHN, n citizen of the United States, residing et Snlt Lake City, in the county oSalt Lelie,

State of Utell, have invented certain new.

and use'rul improvements in Briquets and Processes of Making the Seine, or" which the following n descrigitien, reference being had te the uceeinpei'iyingdrawings, forming :i part liex'eoi'.

My invention has for its object a process of making briquets enty or coed dust by which whether 'the material used be ntlirzrbituminous coul er even lignite, a briquet is produced wliicn is not nii'ected 'by exposure to tire air or by moisture and will 'burn steadily and Without falling te pieces, end my inrenion Consists in the process hereinafter described and claimed, and in tlie product produced by the process.

'lie drawing represents dizigriuninaticzilly an apparatus or plant suitable for carrying mit my process, the drawing being illustrative merely.

in the dra ving l is zi Crusher by which tbe coal, if net already in form of dust, is l'zlfdufred to a iinely divided condition.

2 un elevator er eonveyer for carrying the powdered coal to the drier.

:3 is the drier which iii-y be of any oon.-` venient 'forni butis preferably a rotary coinpurimein drier ueated by e Jfurnace The drier is so ranged and operated as to -not only tlmrouglily dry the coal dust to eliminate :ill moisture butto lient. it strongly, preferablyY as hot as it can be heated Wit-hout causing;L combusti-ou. Frein the drier the dried unil lieeted coal dust is led by' a chute to conmesitien and is provided with stirrers 8 t am liefifted. Preferably two of f; lrettles are used sol that. conand istliese inixi.

lie mixture may be assured. From ille mixing; kettle a pipe with suitable roniroliing valves leads te 'the mixer 5.

"l'lie einer ,.'tion formed in the mixing kettle een i' si oi mineralv oil, resin, a Caustic alkali. pieierebly lye, and sont; stock in the liroimrtions preferably or' Sli per cent. or" mineral oil.. and (325 per cent. each 'if the resin, lye and sf' stock? Tite mineral oil um f be crue-e p i. oleuin residue er other mineral product. Tlie'resin used is prefin which it is .mixed with thel erabiy ordinary commercialv resin, the lye is prefer: biy ordinary pulverized potassium hydroxid and the soap steek may be any kind of animal fut or grease. All of these ingredients should be free 'from Waiter. l ie ingredients mentioned :ire boiled in 'the mixing kettle (S lor from three to thirty minutes or eren longer und ere preferably stirred during cooking operation., When the coinH poeiion becomes stringy it is euiliciently eoolted but the cooking muy 'e continued longer without injury. 'Elie boiling of the composition eliminates any moisture which may be present e; l. by iie action of the lye and resin on the soap stoel; end the mineral oil produces e. composition which becomes -solicl on cooling. Vflien the coxnposiiion has been sullieiently cooked it is allowed to pass into the mixer 5, together with heated coal dust from' lle drier 3, 'the proportions being preferably 8 parte of the composition te parts ef the eoaii dust. y

The mixer if is steam jacketed or ether- Wise heated and is kept het during the mii;- ing. A. small quantity oi' sooty preferably added either .to the vconipesition before it is drawn from the mixing tenir or to the coul dust as it enters tire mixer. The ifi used rfor the purpose/of increasing the resistance er" the linislied briquet to water. It is used preferably in the proportion er' about. l part soot to 9S) parts of the cornpesition but e. slightly greater or smaller proportion muy. be need with goed: results. 9G

Rroni the mixer the roel dustl having the above described composition thoroughly in*- l eorporeted'witli ir, rnd still highly heated is led by u sliert chute tl te e briqueting nu chine l0 by which it is compressed under suitable pressure into briquets or' any lesired shape or size. is the briquets leave tlie briqueting machine they ere cooled by exposure to the air end become 'Solid and Very bard. Wi-oni the briqueting machine the briquets are carried by e cenveyer or elevator l1 to e. etui-:ige bin 12j it is essential to the process that the coinposition used shrill be liquid 'only w'lien het and minable' of' solidii'yineon cooling and slmll be free from waiter, and that the coal. dust simil be free i'roni water and hoi, and that nothing; "be added to the mixture which will abso'rbknieisture. The coal dust may be slack coal or eulm which is of solittle Value as not to pay for transportation or nniy be formed by crushing anthracite, bituminous ree will or lignite. -l'he hriuueis formed by the described process when made frein iin- 'lhucite er lignite eolie readily and hurn wilheui lurnnng' drinker.
